SPECIFICATION forming part of Letters Patent No. 534,006, dated February 12,1895.

Application filed September 10, 1894. Serial No. 522,675. (No model.)

.To all whom it. may concern/.- l

Be it known that I, JAMES POWELL, a citizen of the United States, residing at Avondale, in

Vthe county of Hamilton and State of Ohio,

being had to the annexed drawings, whichl form part of this specification.

The object of this invention is to improve the construction, diminishthe cost of manufacture, and increase the efficiency and utility of the peculiar formof up-feed sight-lubricator described and claimed in Letters Patent N o. l1:63320,granted to me November 17, 1891; the first partof my present improvementsbeing confined to an auxiliary condense-water pocket, which supplies water to the sight glass of the device.

The second part of my present improve: ments consists inl providinga special shut off between the live-steam pipe of the condenser, and the top of the sight chamber of the lubricator.

The third part of my present improvements consists in providing means for insuringa better discharge'of lubricant from the auxiliary oil-cup to an engine cylinder.

The fourth part of my present improvements consists in a novel and efcient dis-v charge Iof condense Water from the condensers' into the main-,oil-chamber, or fount, so as to prevent the contents of said chamber being siphoned out, in certain emergencies. In the annexed drawings, Figure 1 is a sectionized elevation of my improved lubricator. Fig. 2V is a greatly enlarged axialsection through one of the injector valvesrand its accessories. Fig. 3 is a plan of a portion of the lubricator. Figs. 4. and. 5 are enlarged vertical-sections of ytwo different forms of the Water-trap of the device. Fig. 6 is an lenlarged horizontal section through a portion of one side of the reservoir or fount.

The reservoir or oil-fount A, heads B, B', common water-channel b, central opening b', valve b, counterbores b,condensers C, C', steam-tubes c, c, steam-pipe D, branches d, connection d', oil-discharge pipe E, valve F f, injector-nozzle G g, sight-chambers H, H', vent valve N, and auxiliary oil cups O, O',

being the same in general construction and operation as those described in my patent just referred to, except as tocertain improvements hereinafter set forth, require no further explanation in this specification.

The opening b', of water channel b, communicates with a nipple I, having `one or more lateral-ports ,-and screw threaded at its lower end to permit a ready attachment of a waterdischarge tube J, that reaches down nearly to the bottom ot' the fountA, so as to conduct into the latter all Water-that generates within the condensers C, C. Attached to this tube, as seen in Fig.` 1, is a cup K,whose open, upper end is a sufticientdistance below the top of the fount to permit a free passage of steam or air, in certain emergencies. In this construction, the tube is run into the nipple as far as the thread on said tube will go, and the passage above the top of the-cup is determined accordingly, but, as seen in Fig. 4, the cup is also screwed to the tube, and the latter is advanced or elevated' until itcomes in contact with thepfount; channels k being provided to takethe place of said passage; but

in the modification, seen in Fig. 5, the cup is attached tothe tube bya pin j, anda ring la is fitted looselyaround said tube, to determine the distance between said cupand the bottom of the nipple. Y

The tubes L, L', that supply oil to the sightchamber nozzles, inthe usual way, are open at top, but connect at bottom kwith side-passages Z, as more clearly seen inFig. 6. From these side-passages, other channels Z lead to the nozzles; the devices LZ Z being integral with the fount A. VFurthermore,the vertical ltubes L, L', are situated at the side of channel b, asseen in Fig. 3, plugsZ. beingscrewed into the top of the fount and directly above the open, upper ends of said tubes.y These plugs can be unscrewed at any time,-to enable the removal of sediment from the oil-tubes, and are more fully described and claimed in my Patent No. 348,170, issued August 24, 1886.

The sight chambers communicate, at top, by short, vertical ducts h, with enlarged bores h of the heads B, B', at the ends of which bores are seats for shut oif'valves f, one of these valves being seen in Fig. 2. Valve f is carried by the spindle portion f', of a screw--l threaded stem F. A channel B, of some- IOO what greater diameter than the spindle leads from this bore h to a Water-pocket?, which is connected to a more elevated pocket P', by an inclined passage p, this upper pocket P, beingin communication solelywith the steamtube c.

R is a bore, leading from the pocket P into the oil-discharge pipe E, and traversed by the snugly-litting injector-nozzle G, having a small, longitudinal passage g, whose steamreceiving end is at all times Within said pocket, although one or more external flutes or grooves of the nozzle may be used, instead of said passage g.

The auxiliary oil-cup O is secured tothe upper side of the oil-discharge pipe E, and has a bend or elbow o, into which latter is screwed a short pipe o'. By this arrangement, the pipe 0 gives direction to the oil which is driven forward by steam issuing from the nozzle G, and also prevents the lubricant being blown up and out of the auxiliary reservoir O when a cock or valve of the latter is opened.

The dotted circle a in Fig. 3 indicates where a filling-plug may be screwed into the top of the fount, but it can be charged in the same manner as described in my Patent No. 468,320, issued November 17, 1891.

From the above description it is evident that as fast as steam is condensed within the vessels C, C', the water thus generated will traverse the common channel b, and when valve b" is opened, will descend the tube J, escape at the lower end thereof, and thereby ind its way into the fount or reservoir A. Consequently, this condense water will gradually displace the oil, and as the lubricant is elevated, it flows over the open, upper ends of the supply tubes L, L', descends within them, and then enters the side passages l Z. The oil then traverses the passages Z l', ascends within the sight-chambers H, H', passes through the duct h into the bore h', and as soon as valve f is opened, the oil traverses the channel B", and naturally collects within the upper portion ot the water pocket P, the lower portion of which is constantly filled with condense water.

The live steam, that descends the pipe c, and enters the upper pocket P', iiows down the inclined channel p, into the lower pocket P, and being now broughtin direct contact with the oil, ejects it along the nozzle-channel g, and thus drives the lubricant into the discharge pipe E. The oil is finally conducted into any piece of machinery, dac., with which the pipe E communicates; but usually it is connected to one of a pair of locomotive cylinders, for which service this lubricator is especially adapted.

1 If, from any cause whatever, an unusual draft should be made on the fount, and more oil be extracted from it than the engine actually needs, the oil will soon be lowered to the level of the nipple-ports i, and the very instant this level is reached, live steam, or

air, will flow through said ports, and iill the upper portionof said fount and all passages and other channels communicating therewith. Therefore, the flow of lubricant is automatically cut ofi', and all danger of siphonage prevented; but when this unusual draft ceases, the oil is again gradually displaced by the condense water, and the normal action'of the lubricator is resumed.

The drawings show an oil fount having a pair of separate and distinct condensers, so as to render the lubricator especially adapted for locomotive use where an independent supply is required for each cylinder, but it is obvious that the same general construction would apply equally as well to a single condenser for a stationary engine. Finally, it is also obvious that all the functions of nozzlechannel g could be performed by a groove cut along the upper part of the bore R.

I claim as my invention- 1. The combination, in a lubricator, of a reservoir A, havinga condenser C; an oil-discharge pipe E; a water-channel I), near the top of said reservoir, and leading to said condenser; a nipple I, having a port i, and communicating with said channel b by a valveguarded opening b; a water-discharge tube J, depending from said nipple; and a cup K, carried by said tube; the receiving end of said cup being above the level of said port t', substantially as herein described.
